When an OS is installed,
hostname may or may not appear/change automatically.
There
are two scenarios:
Scenario
1: iDRAC is not showing the latest hostname once you install an OS.
You need to install OMSA or iSM along with the iDRAC to get the hostname
reflected.
Scenario
2: iDRAC had a hostname for a specific OS and another different OS
has been installed and still the hostname is appearing as the old
hostname without overwriting the hostname. The reason behind, hostname
is an information which is coming from the OS, iDRAC only saves the
information. If there is a new OS has been installed, iDRAC does not
reset the value of the hostname. However, newer versions of the OSs
are capable to update the hostname in iDRAC during the 1st OS startup.
How to find an iDRAC
IP address for a blade server?
NOTE: The Chassis Management
Controller (CMC) option is applicable only for Blade servers.
Using CMC web interface:
Go to Chassis > Servers > Setup > Deploy. In the table that is displayed,
view the IP address for the server.
Using the Virtual
Console: Reboot the server to view the iDRAC IP address during
POST. Select the "Dell CMC" console in the OSCAR to log in to CMC
through a local serial connection. CMC RACADM commands can be sent
from this connection.
For more information on CMC RACADM
commands, see the Chassis Management Controller RACADM CLI Guide available at www.dell.com/cmcmanuals.
For
more information on iDRAC RACADM commands, see the iDRAC RACADM CLI Guide available at www.dell.com/idracmanuals.
On the main menu, highlight the server, press the check
button, select the required server, and press the check button.
How to find the CMC
IP address related to the blade server?
From iDRAC web interface:
Go to iDRAC Settings > CMC. The CMC Summary page displays the CMC IP address.
From the Virtual Console:
Select the "Dell CMC" console in the OSCAR to log
in to CMC through a local serial connection. CMC RACADM commands can
be issued from this connection.
$ racadm getniccfg -m chassis
NIC Enabled = 1
DHCP Enabled = 1
Static IP Address = 192.168.0.120
Static Subnet Mask = 255.255.255.0
Static Gateway = 192.168.0.1
Current IP Address = 10.35.155.151
Current Subnet Mask = 255.255.255.0
Current Gateway = 10.35.155.1
Speed = Autonegotiate
Duplex = Autonegotiate
NOTE: You can also perform
this using remote RACADM.
For more information on CMC RACADM commands, see the Chassis Management Controller RACADM CLI Guide available at www.dell.com/cmcmanuals.
For more information on iDRAC RACADM commands,
see the iDRAC RACADM CLI Guide available at www.dell.com/idracmanuals.
iDRAC network connection
is not working.
For blade servers:
Ensure that the LAN cable
is connected to CMC.
Ensure that NIC settings,
IPv4 or IPv6 settings, and either Static or DHCP is enabled for your
network.
For rack and tower servers:
In shared mode, ensure
that the LAN cable is connected to the NIC port where the wrench symbol
is present.
In Dedicated mode, ensure
that the LAN cable is connected to the iDRAC LAN port.
Ensure that NIC settings,
IPv4 and IPv6 settings and either Static or DHCP is enabled for your
network.
Shared LOM not functional after enabling Link Aggregation Control Protocol
(LACP).
The host OS driver for the network adapter must be loaded before LACP is enabled. However, if a passive LACP configuration is in use, the shared LOM may be functional before the host OS driver is loaded. See the switch documentation for LACP configuration.
NOTE: Shared LOM IP of iDRAC is not accessible in pre-boot state when the switch is configured with LACP.
Inserted the blade
server into the chassis and pressed the power switch, but it did not
power on.
iDRAC requires up to
two minutes to initialize before the server can power on.
Check CMC power budget.
The chassis power budget may have exceeded.
